Shaba National Reserve, with its great rocky kopjes (isolated hills), natural springs and doum palms, is the most physically beautiful of the reserves, and you'll have it almost to yourself, but it often has less visible wildlife. The open savannahs, scrub desert and verdant river foliage in Samburu and Buffalo Springs virtually guarantee close encounters with elephants and all the other wildlife. The best wildlife viewing is almost always along the banks of the Ewaso Ngiro in Samburu.
